Monitor migrated workloads
You can view logs and metrics from your migrated workloads in the Google Cloud console.
You can also view logs from the command line with
kubectl
.
You can execute bash
commands on the container with your migrated workload. For
more, see the Troubleshooting topic.
View metrics on the GKE console
The GKE console and Cloud Monitoring provide a suite of tools to monitor your containers. To get started:
- Open GKE Workloads
- Click the name of the workload you would like to monitor.
From here, you can see details about this workload, including aggregate graphs of performance across all Pods.
View logs in Cloud Logging
Once you enable monitoring, you can view workload logs in the Cloud Monitoring user interface.
You can use Cloud Logging to view logs for the following aspects of your migration:
- Logs written to
stdout
by processes launched byinit
. - The content of var/log/syslog.
- Optionally, application logs written to the file system.
You can view system logs that are in Cloud Logging from the Google Cloud console. To do so:
- Open GKE Workloads.
- Find your workload and click its Name. The Deployment Details page appears.
- Find the row labeled Logs and click Container logs.
This loads Cloud Logging, showing logs for this workload only.
View logs in kubectl
You can use kubectl
to retrieve logs from a running container. You can also
monitor the progress of export from short-term to long-term storage.
To view the logs for a pod:
Find the name of your pod from the output of
kubectl get pods
. In the example below, the pod's name issuitecrm-app-0
.kubectl get pods

kubectl logs
